1.创建项目helloWord，并添加Struts2能力（添加相应的jar包）

commons-fileupload-1.3.jar

commons-io-2.2.jar

commons-lang3-3.1.jar

commons-logging-1.1.3.jar

freemarker-2.3.19.jar

javassist-3.11.0.GA.jar

ognl-3.0.6.jar

struts2-core-2.3.16.jar
xwork-core-2.3.16.jar

2创建action包，并在包下创建HelloWord.java

package action;

public class HelloWordAction {

private String
message;

public String getMessage() {

return message;

}

public void setMessage(String message) {

this.message = message;

}

public String execute() {

this.message = "我的第一个Stuts2程序";

return "success";

}

}

3.修改index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

<head>

<title>My JSP 'index.jsp' starting page</title>

</head>

<body>
<h3>mesage:</h3> ${message}
</body>

</html>

4.修改web.xml文件为：

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

<display-name>hello</display-name>

<filter>

<filter-name>struts2</filter-name>

<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>

</filter>
<filter-mapping>

<filter-name>struts2</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>
<welcome-file-list>

<welcome-file>index.html</welcome-file>

<welcome-file>index.htm</welcome-file>

<welcome-file>index.jsp</welcome-file>

</welcome-file-list>
</web-app>

5.配置Struts.xml

<?xml
version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts PUBLIC

"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"

"http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>

<package name="hello" namespace="/hello" extends="struts-default">

<action name="test" class="action.HelloWordAction" method="execute">

<result name="success">

/index.jsp

</result>

</action>

</package>

</struts>
